Application filed May 9, 1910. Serial No. 560,269.

To all whom it may concern: I

Be it known that I, J FRANK ANDRES, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Measuring Devices for Gas-Machines, of which the following is a specifica- .tion, reference being had therein to the accompanying drawings.

This invention consists in the provlsion of a measuring devlce that is particularly 4 adapted to be utilized in connection with a gas machine in order to govern the amount of hydrocarbon oil to be delivered to a carbureter in which the vapors of the oil are mixed with air to form a combustible gas.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur, Figure 1 is a side elevation of the measuring device embodying this invention; Fig. 2 is a sectional view on the line 22, Fig. 1; Fig. 3 is a sectional view on the line 3 3, Fig. 3; and Fig. 4 is a top plan view of the receiving cup.

The casing 1 of the measuring device is preferably formed of metal and is provided with an inlet tube or pipe 2, which isconnocted by any suitable means to a pump (not shown in the drawings) that forces the hy- I drocarbon oil to said device, said pump be- 1 oil to flow from said cup into the interior of casing 1. Aslide 6 is pivoted by means of a. screw 7 or the like tothe bottom of cup 3 and is arranged to open or to close said orifice. A projection or button 8 borne by slide 6 protrudes through orifice 5 and afiords a means for moving said slide.

A valve-stem 9 is fastened by any suitable means tocup 3, and passes through a perforation in a guide 10 that projects from Y the inner wall of easing 1. An inverted cup 11 is attached to stem 9 by means of a pin 12 or the like and is disposed above opening 13 of an outlet pipe 14: projecting from the bottom of casing 1, said pipe being connected to the carbureter (not shown). A member 15 extends from the interior of said cup into opening 13 and guides the movement of said cup toward and away from seat 16 that encircles said opening. Cork 17 or other suitable material is placed around member 15 within cup 11, in order to engage seat 16 when said cup is moved toward said seat in the manner hereinafter described said member being provided with openings 18 to allow the liquid within casing 1 to flow through opening 13 whencup 11 is moved away from seat 16.

A lever 19 is pivoted at 20 to a boss 21 that projects from the inner wall of casing 1. One end of said lever bears a roller 22, which underlies cup 3, a weight 23 being attached to the other end of said lever in order to hold said roller in engagement with the bottom of said cup. When cup 3 is empty, the pull of weight 23 forces said cup upwardly within tube 2, thereby moving cup 11 away from seat 16 with the result that the liquid within casing 1 is allowed to flow through openings 18 into opening 13, but when the liquid enters tube 2 and fills cup 3, said cup 3 descends against the pullof weight 23 and causes cup 11 to move toward seat 16, wherebythe cork 'in cup 11 engages said seat and closes the opening 13. Cup 3 remains in its lowered position until all of the liquid therein flows through orifice 5 into the interior of easing 1. Weight 23 then raises cup 3 with the result that cup 11 moves away from seat 16 and allows the liquid in casing 1 to flow through openings 18 into opening 13 of the outlet pipe 14.

The'amount of hydrocarbon oil that is allowed to discharge through the outlet pipe 14 each time the cup 11 is moved away from seat 16 is regulated by means of an adjustable tube or gage 24. Said tube 24 passes through an opening in lug 25, which projects from the top of easing 1, and extends through an opening in lug 26 borne by the bottom of said casing. Tube 24 isarranged to fit snugly in said lugs in order to be held'in any desired position and is provided with apertures 27 which communicate with the interior of casin 1. When the liquid flows into the interlor of casing 1, it fills said casing to the level of apertures 27 in tube 24, said apertures being held at any desired elevation within said casing in order to allow a predetermined amount of the liquid to discharge through pipe 14. Any excess of liquid that enters the interior of casing 1 previous to the raising of cup 3 in the manner hereinabove described flows through apertures 27 into tube 24 from which it discharges to the source of liquid supply. The upper end of tube 24 projects above casing 1 so that said tube can be moved upwardly or downwardly in order to'raise or lower apertures 27 within said casing. A cap 28 is attached to the upper end of said tube and prevents the vapors of the hydrocarbon oil from escaping from said tube. A cap 29 encircles'tube 24:, and is screw-threaded to fit on the screw-thread ed portion of lug 25. Said cap 29 presses packing 30 against the end oflug 25 and prevents the vapors of the hydrocarbon oil ,from escaping from the interior of easing 1. The lower end of tube 24 protrudes into the interior of pipe 31 that is connected to lug 26, said pipe 31 being connected to pipe 32 which leads to the source of liquid supply (not shown) by means of a coupling 33. or the like.

In order to afford a convenient means by which the elevation of apertures 27 can be observed from the outside of easing 1, said casing isrprovided with an opening 34 or a plurality of such openings, each opening 34 being covered with a piece of glass 35. Said glass 35 fits into a ring 36 that projects from casing 1, said ring being screw-threaded internally to receive a'screw-threaded ring 37, which holds said glass firmly in place and prevents the liquid from leaking through opening 34. A cap 38 fits over ring 36 and protects glass 35. Each opening 3 1 atfords a means for obtaining access to the interior of easing 1 in order to actuate the slide 6, or for any other purpose. If desired, the tube 24 can be graduated to indicate the amount of liquid that is measured by the device.

The operation of the device is as follows:

Each discharge stroke of the pump forces a quantity of hydrocarbon oil to tube 2. The oil fills cup 3 and sleeves 4 and lowers said cup, thereby forcing cork 17 against seat 16 to close opening 13. If a larger amount of oil enters tube 2 than is necessary to fill cup 3 and sleeve 4, the excess of oil runs down the outside of said cup into the interior of easing 1. The oil in cup 3 discharges through orifice 5 into the interior of easing 1 and fills said casing to the level of the apertures 27 in tube 24, said apertures being set at the desired elevation to allow a predetermined amount of oil to be measured in said casing. The superfluous amount of oil that enters casing 1 flows through apertures 27 into tube 24; which discharges same backto the source of oil supply. When all of the oil in cup 3 drains into casing 1, weight 23 lifts said cup thereby raising cup 11, with the result that cork 17 moves-away from seat'lG and allows the oil in said casing to discharge through pipe 14 to the carbureter before the next stroke of the pump forces another quantity of oil to tube 2.
